Uninhabited Planet Survive 19

Human colonization of extraterrestrial worlds is a subject on the forefront of the minds of many people; scientists and others alike. Human beings are the most adaptable species known to exist. With the help of modern technology, we are capable of surviving at the extremes of elevation, deep under the ocean, in the hottest and coldest climates on Earth, and even in space, beyond the protection of Earth's atmosphere and magnetic field. Some believe that extraterrestrial colonization will be the key to man's long-term survival, while others think the whole idea is nothing more than science fiction. Will we one day depart our home planet, or has mankind already reached the frontier of exploration?

The first mention of a human colony outside of Earth was by author, historian and clergyman Edward Everett Hale in 1869. Since then, space habitation has been a very popular theme in science fiction works. Only recently have scientists begun to seriously consider the possibility of humans leaving the home planet for good. One of the many reasons justifying an effort to leave Earth is the fact that it is impossible for the human species to survive here long-term.

Destruction of the Sun

Although there are many more imminent threats to our survival, such as rapid climate change, nuclear war, or a hugely destructive natural disaster, what will ultimately and certainly destroy us is the death of the sun around which we orbit. Like all stars, our sun has a finite lifespan; specifically, ours has about five billion more years before it will run out of nuclear fuel and begin to expand. During this initial expansion, the sun will engulf the Earth and destroy it.
